Investigation into Higher Ratios of DBF Compared to Denatured Lysozyme to Determine the Chaperone Activity of DBF

Disulfide Bond Forming Enzyme (DBF) is a unique chaperone protein found in the hyperthermophile Sulfolobus solfataricus. DBF has the ability to chaperone disulfide bonds without the presence of cysteine, which separates it from other disulfide chaperones, implying a novel mechanism of action. DBF is overexpressed in E. coli, purified by immobilized metal affinity column chromatography, and analyzed via SDS-PAGE. One determines DBF activity by how well it acts as a molecular chaperone. By measuring the activity of refolded lysozyme by UV-Vis spectroscopy in the presence of DBF, one can monitor the ability of DBF to correctly refold disulfide bonds. In order to understand DBF’s unique mechanism, we are interested if a higher ratio of DBF to denatured lysozyme is able to refold disulfide interactions.
